Please advice, how to get e-commerce products to the first page

Hey guys,
I have products from my e-commerce site on the page 3 and 4 of G for the keywords that I choose. What can I do to get them to the first page? I'been told that I should get editorial backlink and web 2.0 articles pointing to my products. Can I buy 30 PR9 backlinks to all my product pages and 60 PR9 to my homepage? Is this the best way to get products to the first page?
I would really appreciate your advice
Thanks

Have you tried adding reviews to your products?

Yes, I m working on that but I only have a few reviews. I was told that I should get backlinks to the product pages? Is that correct?
